APPARATUS FOR FINISHING KNIT FABRICS.

SPECIFICATION formingpart of `Letters Patent No. 595,893, dated December 21, 1897,. Applicationliled December 5, 1896. Serial No. 614,566. (N o model.)

To all whom it may concern:

Be it known that I, PAUL ScHLossMANN, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Finishing Knit Fabrics, of which the following is a specification.

My invention has relation to apparatus for the finishing of knit fabrics, particularly such fabrics or goods which are of coarse or rough material, and in such connection it relates to an apparatus whereby the fabric is subjected to attrition between two iiat carriers, which carriers are subjected to pressure by passing the same through pressure or feed rollers.

Heretofore knit fabrics-such as stockings, underwear, and the like-have first been formed into desired shape by stretching the same over fiat boards or forms and either drying the fabric thereon or pressing the fabric on the board by placing the board and fabric in a steam-press. Should the fabric thus treated not receive the required luster or 1inish, itis removed from the boards and laid between immovable fiat surfaces and subjected to pressure with or without heat. This method of finishing has been largely unsatisfactory, and particularly so when applied to fabrics knit from coarse or cheap material.

The principal objects of my present invention are, first, to provide an apparatus wherebya high finish may be given to knit fabrics irrespective of their quality or texture and without the application of heat thereto; second, to provide an apparatus for finishing knit fabrics which consists in subjecting the fabric to attrition between two at carriers during the passage of said carriers through pressure or feed rolls and without the application of heat to said fabric, and, third, to provide an apparatus for the finishing of knit fabrics which consists, essentially, of two Hat boards or carriers between which the fabric is placed and a series of two or more pressure or feed rolls between which the boards or carriers are caused to travel.

My invention, stated in general terms, consists of an apparatus for finishing knit fabrios, substantially as hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which- Figures 1, 2, and 3 represent, diagrammatically and in section, the apparatus for carrying out my invention of finishing knit fabrics embodying main features of my invention and illustrating, respectively, the relative positions assumed by the carriers and fabric as the carriers pass through the pressure or feed rolls.

Referring to the drawings, a and a represent two rolls, which may be either pressure or feed rolls.

b and b represent two fiat boards or carriers adapted to travel between the rolls a and a', and O represents the fabric placed between the boards or carriers b and b and adapted to be finished thereby during the passage of said carriers between said rolls a and cd, as hereinafter more fully explained.

In carrying out my invention of finishing lknit fabrics the fabric C is first placed between the flat boards b and b', which boards may be of pasteboard, wood, or any other suitable material, glazed or unglazed. The ends of the boards b and b are then inserted between the rolls a and ce', as indicated in Fig. l, the meshes of the fabric at that end of the boards being thereby compressed, while the boards b and b" assume an angular position with respect to each other. The boards and fabric are then fed through the rolls until they next assume the position shown in Fig. 2, wherein the meshes of the fabric are compressed and lie between the boards b and b', which have assumed a substantially parallel position with respect to each other. As the boards and fabric leave the rolls, as indicated in Fig. 3, the last end of the fabric is compressed and the boards assume an angular position with respect to each other, which position is opposite to the initial angular posicompression and expansion of the fabric rubs ICO or abrades the meshes against the boards,and thus the fabric takes on a high polish or luster,which may be increased, if desired, by passing the boards and fabric again between the rolis a and a' or between two similar rolls located in advance of said rolls a and a. The rolls a and a' and boards b and b need not be heated, and in practice I have found thatheating the rolls or carriers does not increase or lessen the finish or luster on the fabric caused, as above described, by the attrition of the meshes of the fabric upon the boards or carriers.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
